Abstract

We provide the first record of the non-native Megachile apicalis Spinola (Hymenop-tera: Megachilidae) in Illinois. Thirty M. apicalis specimens were collected in the summer of 2018 in a highly urban area of Chicago, IL, USA. Our findings suggest that the range of M. apicalis appears to be rapidly expanding across North America, inward from both the East and Western Coasts. Megachile apicalis in Chicago has a broad activity period, can take advantage of abundant non-native floral food resources and has competitive nesting behavior, all of which may facilitate its successful establishment in disturbed urban envi-ronments, as well as its continued spread across North America.
